The 13-year-old student who was isolated in a computer room at an Aberdeen secondary school for five months has returned after spending months at a special institution. Chan Sin-ting returned to Po Leung Kuk Wai Yin College in Tin Wan, Aberdeen, after the sponsoring body hired a teaching assistant to help her reintegrate in class. A kuk spokesperson said Chan and her family wanted her return to study at the school. The South China Morning Post revealed in October how teachers at Po Leung Kuk Wai Yin College leaked a tape of a meeting on which a voice, allegedly that of principal Cecilia Yeung Mi-kuen, instructed them to ignore the girl isolated in a computer room. The teenager was sent to the special school following the incident. The teachers also made a number of allegations against Ms Yeung and claimed no action had been taken following earlier complaints. The kuk launched an investigation after the Post's October story and the Education and Manpower Bureau pledged to monitor the investigation. Teachers, who are awaiting the outcome of the kuk inquiry, said Ms Yeung had been on sick leave and had been due to return to work this week but had extended her leave until December 17. They said the sponsoring body had sent education officers to meet them in a bid to improve school administration and staff welfare, but added their major complaints had not yet been dealt with. The Education and Manpower Bureau (EMB) revealed the sponsoring body's investigation team had found there to be 'areas of inadequacy' in the principal's treatment of the pupil and her communication with staff, and that it was due to submit its report this month.
